  • Publication number: 20090001633
    Abstract: A blow molding apparatus for expanding a polymer tube and a method for fabricating a stent using the apparatus is disclosed. The polymer tube is disposed within a tubular mold, over which a heated ring is made of a material having thermal conductivity greater than the tubular mold is translated. The ring is heated with heated fluid streams applied directly onto an outer surface of the ring, or heated fluid circulated within the ring, or an electrically resistive coil within the ring, or combinations thereof. The heated ring uniformly heats a circumference of the tubular mold that, in turn, uniformly heats a circumferential band of the polymer tube. The heated polymer tube is progressively expanded radially and axially while the ring is translated longitudinally over the polymer tube. The expanded polymer tube can be heat set and cooled prior to removal from the tubular mold.

  • Patent number: 7455155
    Abstract: Impact absorbing assembly for slope protection systems, fitted in the containment and protection screens to guard against stones or other bodies landsliding, comprising two cables arranged in the form of loops, each being cased in a ā€œUā€ shaped tube. The cables are interlaced or arranged in parallel, the loops being fastened together in their upper and lower part by a clamping element compressing the tubes. The cables comprising the invention may be installed taut between the hill anchoring and the protection system, or alternatively, fitted on the mesh support cables with the posts. When an overload occurs on the containment screen, the sudden pull on the cables will force the tubes to become distorted to slide within the clamping elements, the friction leading to a dissipation of energy.

  • Publication number: 20080033523
    Abstract: A medical device such as a stent with a catheter, delivery balloon and an infrared energy source is disclosed. The infrared energy source heats the delivery balloon, and/or the stent to a temperature above body temperature, thereby increasing the flexibility of the stent such that formation of cracks in the stent upon its expansion is reduced or eliminated. Either the delivery balloon, and/or the stent may include an infrared energy absorbing material.

  • Publication number: 20070289117
    Abstract: A method of crimping a stent on a balloon of a catheter assembly is provided. A polymeric stent is disposed over a balloon in an inflated configuration. The stent is crimped over the inflated balloon to a reduced crimped configuration so that the stent is secured onto the balloon. The balloon wall membrane is wedged or pinched between the strut elements of the stent for increasing the retention of the stent on the balloon.

  • Patent number: 6953560
    Abstract: An implantable medical device and methods for making the implantable medical device are disclosed. The implantable medical device includes a substrate. At least a portion of the substrate is coated with a first layer including a polymer containing a drug. A barrier overlies the first layer. The barrier significantly reduces the rate of release of the drug from the polymer, thereby sustaining release of the drug from the medical device for a longer time. The barrier may be a homogeneous layer overlying the first layer, or a number of discrete deposits over the first layer. Alternatively, the barrier may be intermixed with an outer portion of the first layer. The barrier material is biocompatible, and typically has a thickness ranging from about 50 angstroms to about 20,000 microns.

  • Patent number: 6713119
    Abstract: A coating for a prosthesis, for example a stent, and a composition for forming the coating is disclosed. The coating can serve as a primer, allowing substances, such as polymers, to be effectively secured by the prosthesis. Alternatively, the coating can serve as a reservoir, allowing for the local and sustained release of a therapeutic substance to biological tissues. The composition can be formed from an ethylene vinyl alcohol copolymer and a dimethylsulfoxide solvent, with or without a therapeutic substance. Alternatively, the composition can be formed from an ethylene vinyl alcohol copolymer, a dimethylsulfoxide solvent, and a wetting fluid, with or without a therapeutic substance. The composition is applied to a surface of the prosthesis and essentially all of the dimethylsulfoxide solvent or dimethylsulfoxide solvent/wetting fluid is removed or allowed to evaporate to form the coating.
